-The maximum extent of available map tiles. Bounds MUST define an area covered by all zoom levels. The bounds are represented in WGS:84 latitude and longitude values, in the order left, bottom, right, top. Values may be integers or floating point numbers. The minimum/maximum values for longitude and latitude are -180/180 and -90/90 respectively. Bounds MUST NOT "wrap" around the ante-meridian. If bounds are not present, the default value MAY assume the set of tiles is globally distributed.
